That would be nice, but it could be done easier with a var with a limit:
The contact sent a message, it's saved inside a var and adds a timer, if he sends the same message more 3 times or so before the timer triggers, blocks for 'x' time. Something like that
Thanks, and thanks for the idea
P.S. I already made another version, with a new code and now user's able to choose some options with /command, just waiting MenthiX aproval, then if it's worth it ('cause I'm in a brainstorm and ideas can't stop coming
), I'll make a 2.0 version with a GUI
